El Segundo-based toymaker Mattel Inc. continues to reduce the environmental impact of its products and packaging.

The maker of Barbie and Hot Wheels released its Global Citizenship Report on Tuesday. The 62-page document is the fourth edition of the report. The world's biggest toy company issued its last such report in 2009.

Like other consumer-oriented companies, Mattel cultivates an image of a responsible corporation that is committed to the environment and other humanitarian issues.

"As the world's largest toymaker, Mattel produces some of the best-loved and time-tested toys and juvenile products available. With this comes a responsibility and high expectations for safe, high-quality and innovative toys created in a responsible manner," Mattel spokesman Alan Hilowitz said in an email to the Daily Breeze. "We believe that transparency improves performance and builds trust, and feel it's important to share how we are making progress in key areas, like sustainability and responsible operations."

Some of Mattel's achievements highlighted in the report include the following:

Since 2009, Mattel has eliminated more than 90 percent of the nonrecyclable wire twist ties used in its toys - equivalent to 363 tons of material.

In 2010, the company's Hot Wheels factory in Malaysia started using residual sugar cane fiber as an alternative to traditional packaging material.

In 2011, Mattel adopted a more environmentally responsible approach to procurement of paper and wood fiber used in packaging and products.

The change in Mattel's sourcing of paper and wood fiber came after an acrimonious and embarrassing confrontation last year with an environmental group. Greenpeace had accused the toymaker of using a supplier that contributed to deforestation in Indonesian rain forests and destroying the Sumatran tiger habitat.

In June of last year, Greenpeace activists hung a giant banner on Mattel's 15-story headquarters in El Segundo. It carried a message supposedly from the company's popular Ken doll: "Barbie, it's over. I don't date girls that are into deforestation."

The issue was resolved after Mattel cut ties with the controversial supplier and made commitments to increase its use of recyclable paper packaging or sustainable fiber.
